SURVIVAL OF CANDIDA MYCODERMA CELLS UNDER INTENSE LIGHT PULSES TREATMENT ON GLASS USED AS PACKAGING MATERIAL

摘要: Cells of Candida mycoderma were inoculated on glass and subjected to intense light pulses (ILP) treatment for up to 1.27 J/cm2 energetic density and different time at 7 cm distance from the flash lamp. Population reductions higher than 2 log10 colony-forming units per square centimetre (CFU/cm2) were achieved. Calculation revealed a D-value ranging from 0.797*10-3 s to 2.826*10-3 s and a Z-value of 0.69 J/cm2. The study has demonstrated that ILP is a promising treatment for packaging material decontamination and/or sterilisation.
